PURPOSE: A prediction method for oscillation of Madden and Julian oscillation is provided to determine the accuracy of an atmosphere-marine climate prediction system because the already obserbed data dose not affect prediction data of future. CONSTITUTION: A prediction method for oscillation of Madden and Julian oscillation comprises the steps of: extracting a Madden and Julian oscillation signal from data actually measured for past arbitrary time and converting the extracted vibration signal into a coefficient time series value; extracting Madden and Julian oscillation-related components in a place using prediction data of atmosphere-marine climate prediction system and converting the extracted component to coefficient time series value; and improving performance of prediction by regenerating Madden and Julian oscillation-related coefficient time series value from present to the arbitrary future.
